Product Description: Orco Blended Pump Aid is a powder admixture for concrete used in grouting of concrete block and clay brick. Orco Blended Pump Aid will provide slight expansion, retarding and water reducing properties to the grout. The product improves the performance and the placement of the grout. Concrete with Orco Blended Pump Aid will have a water reduction of 10-15%, 8-10% higher compressive strengths and more than two times the shear bond strength. It contains no chlorides or other chemicals, which contribute to corrosion of reinforcing steel. Special mix designs available to meet individual job requirements. Uses: Grouting of Concrete Block and Clay Brick.

Advantages:

• Higher slumps with greater flow
• Higher bond and compressive strength
• Lower water cement ratios
• Slight expansion
• Increased water retention
• Non-Corrosive
• Improved pumping properties

Packaging: Orco Blended Pump Aid is available in 42 # multi wall bags.

Technical Data: Grout mix design should be a minimum of six sacks on cement, 70% washed concrete sand and 30% 3/8" aggregate per cubic yard. Grout ingredients will conform to U.B.C. 24 and A.S.T.M. standards.
Orco Blended Pump Aid is added at the rate of 1% of the total cement content.

Application: Orco Blended Pump Aid is added to the ready mix truck at the job site or it can be pre-blended dry with Orco Blended 70/30 Masonry Grout Concrete Mix. Grout should be ordered from the ready mix plant at a 5-6" slump. Orco Blended Pump Aid will increase the slump 2-4" without any additional water. A slump of 8-10" should be maintained. Batches should be placed within one hour so that as much of the expansion action occurs after the grout is placed. Add slowly for proper mixing. All hose fittings on a grout pump should be watertight to prevent clogging.

Limitations: Grout must be placed within 1-1/2 hours after addition of Orco Blended Pump Aid. Consult an Orco Blended Rep for uses other than grout for masonry units.
